The Norwegian Nobel Committee announced that the prize would be shared by former U.S. Vice President Al Gore and the IPCC for their efforts to "build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change."

Oppenheimer, who has been affiliated with the panel since 1990, said, "The Nobel Committee's recognition of the IPCC is very encouraging to the thousands of scientists over the years who have dedicated large amounts of time for these reports. The recognition makes it clear that expert advice means something."

The IPCC was created by the U.N. General Assembly in 1988 to provide objective policy advice in response to the growing concern about the risk of climate change. Thousands of scientists and officials from more than 100 countries have collaborated on IPCC reports over the past two decades.

Two panel reports presented earlier this year concluded it was very likely that humans were responsible for global warming, and that rising temperatures would likely accelerate if steps were not taken to address the warming trend.
